None of that addressed my point, it only was re-stating what you already believe.
My point is that the hair has no idea whether it's "trapped under sebum" or not. It won't just "stop growing". It's not like the hair is thinking, "sh*t I'm trapped, I better stop growing now".
If you had a heap of hair being "blocked" by sebum, all that would happen is you'd end up with a sh*t-load of in-grown hairs all over your head.
Also, I don't think there's any evidence that shaving your head down accelerates balding. I've had my head shaved for 20 years. Sure, I'm obviously fairly advanced in my balding, but in that time, plenty of my mates that had full heads of hair went completely bald. When I let my hair grow a bit, people often are surprised that I still have hair.
....
anyway ... I thought you might be interested in this little experiment I did. I bought a pore-vaccum type machine last week. I have the link for the exact machine below ... very cheap ... some Chinese piece of crap.
As an experiment, I razor-shaved my head yesterday, like egg-bald and went over it with this machine. I must say, I was quite surprised at the amount of gunk it sucked out of my scalp! It wasn't ridiculous or anything, all in all my 1/3 of a ml I guess. But it was gross and surprising. And it doesn't even work that well. I know because I used it on my nose too ... and got some gunk out. But afterwards I was able to squeeze my nose and get more out. So I know it's not getting everything out, just the top layer.
